Prerequisites
Phys 113, and a basic knowledge of algebra, trigonometry, geometry and a calculator.
Description
PHYS 114 is an algebra/trigonometry based introductory physics course dealing with the topics of electricity, magnetism, light and quantum physics. Emphasis will be placed on the basic principles and
concepts and their applications in everyday technology and in the world’s economy.
Objectives
Successful students will understand how to analyze the processes of nature, what goes on in the world,
and how some technology works, including the basic concepts and numerical estimates.
Grading
Grades will be determined from Recitation, Exams, Labs, and Homework, as follows:
Task
Max. Points
Grading scale
Hour Exams (best 4/5, 125 pts. each)

F: below 600
Total
1000
Recitation includes an in-class group-work problem on paper (10 pts. each, lowest 3 dropped) and an
on-line homework at masteringphysics.com (none dropped). The courseID in Modified Mastering Physics
is MPWYSIN2016F, which is linked through Canvas under Mylab and Mastering. The best 12 lab
scores will be scaled out of 200 points. The lowest of the hour exams, each worth 125 points, will be
dropped. Because lowest scores are dropped, there are no makeup recitations, labs, or exams. The last
hour exam takes place at 6:20 - 8:10 p.m., Tuesday, December 13 (See http://courses.k-state.edu/examschedule.html).

Lecture i>clicker Questions
I will use i>clickers during lecture to help with concepts you are learning. Each day, I’ll pose about
2 to 4 i>clicker questions. For each question there is 0.5 point for participation and 0.5 point for a
correct answer. The questions will be based on the readings and any topics for that lecture. At the end
of the semester, the total i>clicker points will be scaled out of 60 (6.0% of your grade) after dropping
your lowest 5 scores. If you can’t make it to class, there is no make-up. It will be a dropped score. Bring
your clicker to class every lecture.
You can get an i>clicker at a bookstore, or, use one you have for another class, or use one you get from
someone else. Further info about registering your i>clicker is given on an attached sheet.
Laboratory
The laboratory is a required and integrated part of the course, and counts 20% towards your grade.
A passing grade (60%) in the laboratory is required to pass the course. See the lab manual and listen
to your lab instructor for rules and grading procedures. Lab begins during the second week of class.
You do not need to buy any lab manual. The lab information will be found in electronic form on KSOL
before each lab. Address your questions about lab grades and procedures either to your lab instructor or
to Brandon Lohman, the Director of Undergraduate Physics Labs, CW 403.
Credit for Previous Lab Work
Students retaking the course, who have successfully completed the lab must contact Brandon Lohman
in CW 403 (532-1605) prior to the first week of lab to get credit for the previous lab work. There is a
special lab section to enroll in for retakes.
Recitation and Homework
Doing homework problems is an important part of obtaining success in physics, helping you organize
your thoughts, learn the concepts, and apply them.
The recitation is where you can go for help with problem solving and learning concepts. If you have
already attempted some of the HW before the recitation, you will get more out of it. The recitation will
be oriented towards learning and applying ideas in general, not necessarily to particular problems. The
recitation should improve your overall understanding of physics, and help you prepare for exams as well.
There will be two elements to recitation: a “group-work” problem submitted on paper in recitation class
(10 points/week, lowest 3 dropped), and on-line submission of the full assignment at masteringphysics.com
(120 points/semester). The MMP courseID is MPWYSIN2016F.
Group-work: Your recitation instructor (Wysin or Ryan) will assign you to groups of four or less where
you collaborate to make the solution of a written problem in class each week. Every student will write
their own solution, however, they can discuss within the group and also get help from the instructor.
Only one group member’s paper will be selected for grading each week; all group members get the same
grade. You can help your group do its best by participating and making sure everyone understands what
they are doing. Groups will be changed after each hour exam. If you don’t attend the recitation your
group-work score will be zero.
Your group-work problem must show the details of how you solved it: include necessary diagrams,
identify the concepts or physics principles you are using, show the equations you apply, and show
how the numbers with units are inserted after that, and finally, a numerical answer with the correct units.
No credit will be given for just numbers or a yes/no response. Keep in mind that students who do best
on exams are the ones who work carefully, writing things out clearly with well-organized presentation of
the concepts and equations used before inserting numbers. See the problem solving tips on pages 3
and 4, and the Guide to Solving Physics Problem hand-out in KSOL.
On-line HW: Each on-line assignment will be available at www.masteringphysics.com about 10 days
before the associated recitation. The MMP courseID is MPWYSIN2016F. The problems are from the
Giancoli text and other textbooks, as well as Pearson’s “self-tutorial-problems”. The due dates will be
5:00 pm Thursdays. None of your on-line scores will be dropped. You are allowed to work with others
2
(not copying) on your HW, which means discuss the ideas and things you don’t understand, until you
do. Many of the problems have randomized numbers: everybody gets different numerical values. So you
will be happiest if you understand what you are doing. You are not allowed to use solution manuals,
on-line solution websites, Cramster, etc. These are considered unauthorized aids and a violation of
the honor code. The point of homework is to practice thinking, not copying a solution algorithm from
another source.
To get access to the on-line homework you need an access code for masteringphysics.com. However, if
you took PHYS 113 in the last two years then you already have a Pearson account and you do not need
to buy another access code: your MMP login name and password should still work. An access code can
be purchased at the site with a credit card, at the bookstores, or as an option to be included with a
paper text or an e-text. The MMP courseID is MPWYSIN2016F. Your username there can be anything,
but you might use your eID name so you remember it. Enter your WID correctly there so you get credit
when grades transfer to KSOL.
Hour Exams
These take place on some Thursdays at 5:30–6:45 p.m. in CW 101,102,103, except for the last one,
which will be in the final exam time, 6:20–8:10 p.m., Tuesday, December 13, see the schedule. If you
have an official University event, such as participation in a KSU sports team, debate team, etc., that
conflicts with an exam time, you might be able to take that exam early, ask me. There are no makeup
exams, but your lowest score of the five exams will be dropped.
On exams, you will need to show how you solved problems, so it will be good to practice this when doing
your HW, even if it is not necessary for submitting online HW. So for your own benefit, acquire the habit
of writing out the details of your solutions. You can list the given quantities (with their symbols and
values with units) and list the quantity you are looking for (with its symbol and units). Include necessary
diagrams, the equations you applied, show how the numbers with units were inserted after that, and
finally, give a numerical answer with the correct units. Practice thinking while doing your HW, then your
exams will become easier. Remember that on exams, no credit will be given if just the final numerical
answer is given.
The exam problems will be based on the same concepts as covered in the lectures and in homeworks.
Old exams and solutions can be found on the course website. Try to study the concepts and how to
apply them, do not just try to memorize how to solve particular problems. One page on the exam will
be an equation sheet that summarizes the important formulas you may need to do the problems in those
chapters. This equation sheet will be posted to KSOL some days before the exams. Solution keys to the
exams will be posted on the course website.
Final Exam
The Final Exam is the last hour exam, covering Chapters 30 & 31, on Tuesday, December 13, from
6:20 – 8:10 p.m. in CW 101,102,103. If you are satisfied with the grades you have up to that point, then
Exam 5 could be the hour exam that you drop, and your grade will be calculated without it. That means
Exam 5 is optional.
Plan early, keep up with the course, take responsibility for your learning and your grade, and you can get
done with PHYS 114 early! If in doubt, take the final hour exam, it can only raise your grade or leave it
unchanged.
Grades on KSOL
Be aware that the total course grade you see in KSOL during the semester is only an estimate of
your grade. Until all homework, recitation and lab grades are entered, KSOL does not give your precise
grade, due to the low scores being dropped and scaling of points. Only when all components have been
entered, is it correct.
Grades may be contested up to one (1) week after being posted on KSOL - after that they become a
permanent academic record. This applies to both the main gradebook for the course and the gradebook
for the lab.

Tips on doing Physics II homework problems
* Don’t wait until the last minute.
Begin homework assignments several days before they are due.
You can surely do some of them even before hearing about the topic in lecture.
* What’s going on here?
Sketch the situation. Make it seem real for yourself.
Identify desired quantities, their symbols, and their units.
I want to find charge q, in coulombs
List the quantities you know, with units.
I know potential V, in volts.
I know capacitance C, in farads.
Recall the definitions of these items, it may help a lot!
What are the important equations or relations between them?
The charge is given by the capacitor formula. q = CV .
* Get help if you need it.
Being completely stuck is no fun. If you really are getting nowhere, and have no idea what to do
next, you are encouraged to cooperate with other students, or seek help from your instructors.
* What’s my strategy?
What concepts and equations apply?
Briefly state your strategy in words and sentences.
(Pretend you are explaining to another student.)
Write down the equation(s) you will use, in symbols.
* Solve algebraically for the desired quantity.
Still stuck? Did you really draw a diagram?!
You may need to combine some equations, or use trigonometry, that’s OK!
Get the quantity you want on the left of the equals sign, and everything else on the right.
Don’t skip steps.
* Do the arithmetic, with units.
Substitute numbers with units in your equation.
Power P = IV becomes P = (8.0 A)(24 V ) = (8.0 C/s)(24 J/C) = 192 J/s = 192 W.
Keep the units on everything until the end. It’s a useful check.
* Write down the answer, with correct units!
* Does the answer make sense?
Is the number of reasonable size, not excessively large or small?
If you change the given numbers to very simple cases, will you get an expected result?
If you modified the situation into a simpler one, will your approach still work?
* Enjoy the challenge.
Hey, you figured out something new. Now you understand it.
And it wasn’t so simple.
Have confidence, you can do as well or better on the next problem!

Physics Study Hints:
1. Read the textbook, paying attention to the equations and figures.
2. When you take notes in class, don’t just copy equations and diagrams. Listen to the instructor and
write down the ideas behind the equations and diagrams!
3. Study the examples in the book in order to learn how to solve problems.
4. If you don’t understand, formulate a question. Write down your questions so you can ask your
instructor later. Then ask your instructor later!
5. Stop occasionaly and think about what you just read. Try to think of real-life examples where the
physics ideas might be applicable.
6. Look at extra questions and level I problems, just to see if you would know how to answer them. If
so, you have a good grasp of the definitions of basic concepts.
7. If you can’t work a difficult homework problem, try to work a related, but easier one first. Or, try
breaking your problem into steps or parts.
8. Keep in mind, the level II problems usually require you to apply more than one concept. You probably
need to use more than one equation.
9. In physics, the same idea can be expressed several ways: as a picture or diagram, equation, or graph.
Look for the main idea. Think about how the different presentations help you to understand it.
10. Remember, physics isn’t always complicated. Most of the ideas are simple and common-sense.
Laboratory Hints:
1. Work smart, which is to say, efficiently. Check yourself as you go along (hints 3,5,6 above). Do it right
the first time, because you won’t have time to do it over.
2. Write down the names and telephone numbers of your lab partners on your data sheet.
3. Read the lab manual before lab. Figure out what you want to look for, and how you will look for it.
Write this down before you get to lab. (This is the start of your lab report.)
4. In lab, pay attention to the lab instructor’s explanation. Some things aren’t in the lab manual.
5. While taking data, make a graph right away so you can see if your data make sense. Professional
physicists do this all the time. Plot each data point as soon as you’ve finished writing down the number.
This habit can save a lot of trouble later, because you can immediately see what the data are doing!
6. After you have taken a few data points, do a sample calculation for analyzing the data. This will (a)
let you know if your data make sense, (b) let you know whether you understand what you are doing, (c)
let you know if you’ve forgotten to write down any quantities. A sample calculation will save you from
getting home, then realizing that you forgot to get a number.
7. Write down everything on your data sheets. Never rely on your memory. Use pen. Never erase. Cross
mistakes out neatly instead, so you can still read them if you have to. Write down ideas that occur to
members of your lab group, too!
8. Work as a team. Make sure that everyone gets to play with the equipment. Report broken equipment
to the lab instructor, so he can make sure it gets fixed.
9. Graphs on the data sheet may be crude. Graphs in the lab report should be drawn large enough to
see, preferably on a full page. Grpahs and tables must have titles. The axes on graphs must have labels
(i.e., numbers, name of quantity being plotted, and its units).
10. Use words and sentences to describe what you are doing. Correct spelling and grammar are encouraged. Graphs, tables and equations supplement the words. They never replace words.

IMPORTANT STATEMENTS
University Statement Regarding Academic Honesty
Kansas State University has an Honor System based on personal integrity, which is presumed to be
sufficient assurance that, in academic matters, one’s work is performed honestly and without unauthorized assistance. Undergraduate and graduate students, by registration, acknowledge the jurisdiction of
the Honor System. The policies and procedures of the Honor System apply to all full and part-time students enrolled in undergraduate and graduate courses on-campus, off-campus, and via distance learning.
The honor system website can be reached via the following URL: www.k-state.edu/honor. A component
vital to the Honor System is the inclusion of the Honor Pledge which applies to all assignments, examinations, or other course work undertaken by students. The Honor Pledge is implied, whether or not it is
stated: ”On my honor, as a student, I have neither given nor received unauthorized aid on this academic
work.” A grade of XF can result from a breach of academic honesty. The F indicates failure in the course;
the X indicates the reason is an Honor Pledge violation.
My Additional Statements on Academic Honesty
Note that you are permitted to work with (not copy from!) other students on homework problems
(and labs) if you acknowledge cooperation by writing “I worked with (name)” on the assignment. Use of
any kind of solution manual for doing homework is an unauthorized aid. All exams must be entirely
your own work.
Statement Regarding Students with Disabilities
Students with disabilities who need classroom accommodations, access to technology, or information
about emergency building/campus evacuation processes should contact the Student Access Center and/or
their instructor. Services are available to students with a wide range of disabilities including, but not
limited to, physical disabilities, medical conditions, learning disabilities, attention deficit disorder, depression, and anxiety. If you are a student enrolled in campus/online courses through the Manhattan
